I Listen but I Can't Hear

When I was a kid, maybe 6 years old, myringotomy tubes (ear tubes) were placed in my ears because I had some sort of infection going on. In time the tubes were supposed to fall out and the incision that was made for the tubes to be placed would heal up by itself. They did fall out. About a month ago I had a physical. The doctor checked my ears and asked if I had had surgery some time. She said there was a hole in my right ear drum. I sort of freaked out because in all my years of checkups, no other doctor had ever told me this. That's when I realized that the hole is probably why I just hear muffled sounds from my right ear and also, whenever water would get into that it would hurt like hell. For the longest time, whenever I would put headphones on, the right headphone always sounded of lower sound quality. I thought it was the headphones, till now of course. Recently, my right ear's hearing has worsened. It's terrible. If I cover my left ear and someone is talking, I can barely hear a whisper. My mom called the doctor today and I have an appointment in a few days I think. I hope this can be fixed.
